Answer:
x= 20
AD= 23
DC= 23
AC= 46
Step-by-step explanation:
because it's a median that means that x+3=2x-17 solve for x and get x=20 which (I think) means that AD, DC= 23 and that AC= 46

A man weighing 800 N is hanging from a 2 mm diameter titanium wire with a cross-section of 3 x 10^-6 m^2. Will the wire break?
Answers
Answer:
Since stress is greater than ultimate strength, the wire will break.
Step-by-step explanation:
The titanium wire is experimenting an axial load. Ultimate strength equals [tex]2.20\times 10^{8}\,Pa[/tex]. The wire shall break if and only if stress is at least equal to ultimate strength. The equation for axial stress ([tex]\sigma[/tex]), measured in pascals, in the wire with circular cross-section is:
[tex]\sigma = \frac{4\cdot F}{\pi\cdot D^{2}}[/tex] (1)
Where:
[tex]F[/tex] - Axial force, measured in newtons.
[tex]D[/tex] - Cross-section diameter, measured in meters.
Please notice that axial force is the weight of the man hanging from wire.
If we know that [tex]F = 800\,N[/tex] and [tex]D = 0.002\,m[/tex], then the axial stress experimented by the titanium wire is:
[tex]\sigma = \frac{4\cdot (800\,N)}{\pi\cdot (0.002\,m)^{2}}[/tex]
[tex]\sigma \approx 2.546\times 10^{8}\,Pa[/tex]
Since stress is greater than ultimate strength, the wire will break.

[tex](1/5k)^2=1/5^2*k^2[/tex]
[tex]1/25*k^2=\frac{k^2}{25}[/tex]
Answer: [tex]\frac{1}{25}k^2[/tex]
This is equivalent to [tex]\frac{k^2}{25}[/tex]
In decimal form, this is equivalent to 0.04k^2
==================================
Work Shown:
We have the two pieces 1/5 and k, all in the parenthesis being squared.
Square each piece
Squaring the piece 1/5 leads to (1/5)^2 = 1/25, since 5^2 = 25squaring the k value leads to k^2So overall, we end up with the answer [tex]\frac{1}{25}k^2[/tex] which is equivalent to saying [tex]\frac{k^2}{25}[/tex]
In decimal form, this is 0.04k^2 because 1/25 = 0.04

Answers
Answer:
3x + 2y = 540
x + y = 210
Step-by-step explanation:
Giving the following information:
At the county fair, 210 snow cones were sold for a total of $540. Large snow cones (x) cost $3.00 each and small snow cones (y) cost $2.00 each.
We can establish the following system of equations:
x= number of large snow cones sold
y= number of small snow cones sold
3*x + 2*y = 540
x + y = 210

Each employee in a company is either right-handed or left-handed.
32 of the 54 employees are female.
18 of the 41 right-handed employees are male.
Complete the frequency tree for this information.
Answers
Answer:
23 females are right handed and 9 are left handed
Step-by-step explanation:
So to get this answer :
18 OF THE 41 RIGHT HANDED EMPLOYEES ARE MALE.
The statement means that there are 41 right handed employees and 18 of those are male thus the remaining are FEMALE.
To find the number of right handed employees who are female just subtracted 18 from 41 ( becaus etotal number of right handed males is 18 and the total number of right handed employees is 41.)
SO 23 FEMALES IN THE COMPANY ARE RIGHT HANDED.
Because 23 females are right handed that means to get the number of left handed females you subtract the total number of right handed females from the total number of females in the company THUS:
32 - 23 = 9 LEFT HANDED FEMALES

Alice's average mark for 4 Science exams is 68%. Can Alice score enough marks in a fifth exam so that her average mark increases to 75?%? Give reasons.
Answers
Answer:
It is not possible for Alice to score an average of 75% because what she needs to score in the fifth exam exceeds the maximum possible score.
Step-by-step explanation:
She scored an average 68% in all 4 exams.
This means; (68% + 68% + 68% + 68%)/4
Now, a fifth exam is added and we want to know if her average can now be 75%.
Thus, let the score in the 5th exam be x and we now have;
(68% + 68% + 68% + 68% + x)/5 = 75%
Multiply both sides by 5 to get;
(68% + 68% + 68% + 68% + x) = 375%
272% + x = 375%
x = 375% - 272%
x = 103%
The maximum score is 100% and therefore it is impossible for her to score 103%. Therefore it is not possible for Alice to score an average of 75%
